ROTARY ENGINE.

Specification of Letters Patent.

Patented Apr. 25, 1911.

Application filed April 5, 1910. Serial No. 553,515.

To all whom it may concern:

Be it known that I, JOHN NORIN, a subject of the King of Sweden,residing at J ersey City, in the county of Hudson and State .of NewJersey, have invented new and useful Improvements in Rotary Engines, ofwhich the following is a specification.

This invention relates to motors or more especially to that class ofmotors known as rotary engines which are adapted to be driven by steamor gas and are provided with a rotating piston.

The present invention is adapted to provide a backing or purchase forthe operating fluid which is confined between the said backing orpurchase and the rotating piston so that the latter is impelled forwardby the motive fluid confined behind it, but by means of certainmechanism this backing is at regular intervals removed or disposed withso that the piston passes on while the backing is again brought inposition to affect its work.

These and other objects and details of the invention are more fullyexplained and described in the following specification, set forth in theclaims and illustrated in the accompanying drawings, where:

Figure 1 is a side elevation of the motor showing the mechanism foroperating the backing for the motive power. Fig. 2 is a similar viewwith the side plate removed to illustrate the operation of the interiorof the motor. Fig. 3 is a longitudinal sectional view. Fig. 1 is a sideview of a modified form of the motor. F ig. 5 is a cross sectional viewof same. Fig. 6 is an end view of the modified form.

In the operation of a motor such as shown in the accompanying drawings,it is preferable that two cylinders 10 and 11 are employed and which areconnected at adjacent sides so that the steam or other motive fluid mayenter the pipe 12 and pass into a chamber 13 having therein a rotatingvalve or cut off 14 which opens and closes inlet ports 15 and 16 andadmits the steam to the respective cylinders 10 and 11. These inletports are immediately above a horizontally arranged disk 17 intersectingboth of the cylinders and playing in a groove 18 of the hubs 19 at thecenter of each cylinder and carrying the pistons 20 and 21. Thesepistons 20 and 21. fill the space between the hub and the inner surfaceof the cylinder and act as a barrier to prevent the steam from passingfrom one part of the cylinder to the other and in the disk 17 is cut anopening 22 to permit of the passage of one of the pistons as it rotatesand as the disk intersects the interior of the cylinder as shown inFigs. 2 and 3, it normally acts as a backing for the motive fluid whileit acts on the pistons until the piston has passed around the cylinderand approaches the disk when the opening 22 is brought into position.

The shafts 23 of the hubs 18 are provided with worm gearing 24: and ashaft 25 which causes them to work in unison and this shaft also carriesa worm wheel 26 gearing with a similar wheel 27 on a shaft 28 whichcarries and rotates the disk 17 so that the opening 22 passes into eachcylinder as its piston 20 or 21 is about to pass the disk. The balanceof the disk therefore, becomes a backingfor the motive fluid which issupplied by means of the inlets 15 and 16 between the disk and thepistons so that the latter are moved forward and the fluid in advance ofthem is exhausted from the ports 29 and 30 at one side of the motorframe.

Themodified forms shown in Figs. 4, 5 and 6 dispenses with the wormgearing and in its place are employed a number of hell crank levers withballs and sockets to accomplish the same result. The ends of the shafts23 carry socketed arms 37 and in the sockets are held the balls of arms31 projecting from a sliding rocking shaft. From this shaft alsoprojects a depending arm 32 having a ball working within a socket at theupper end of an arm 3 1 also carried by a rocking and sliding shaft 33.The other end of this shaft 33 carries an arm 34 connected with an arm37 located at the lower end of the stem of valve 35 and when the shafts23 rotate the arms 31 are rocked and shifted giving a similar motion tothe arm 32 which in turn rocks and shifts the shaft 33 and the arms 34and 34 and finally rotates the arm 37 and the valve stem. The arms 37and 37 are provided with counterweights and the valve 35 is similar tothe valve 14 above described. The reversing of this motor isaccomplished by means of a toothed bar 40 operated by means of a lever40, the teeth of which gear with the teeth of a shift ing disk 42adjacent to the rotating disks 4:2 which are carried by the shaft 23 anddescribed heretofore but the latter valve operating mechanism producesless friction and may be found more desirable.

In assembling the frame of the motor, a semi-circular framing 36projects from each side of the motor to accommodate the disk 17 and inpractice, it Will be found unnecessary to provide anypacking for thisdisk as the steam or vapor used to dry the device Will be found adequateto prevent the leakage or passage of vapor from one part of the motor tothe other.

It is obvious that the motor may be other- Wise modified and its partsaltered, Without departing from the essential features above described.

What I claim as new and desire to secure by Letters Patent is:

1. In a motor, the combination With adjacent cylinders, of pistonsrotating in the cylinders, a valve mounted on a stem and a disk carriedby the valve stem and intersecting the space Within the cylinders, andhaving a passage for the pistons to pass through; and driving meansconnecting the pistons With the valve stem.

2. In a motor, the combination with adjacent cylinders, of a valvemounted on a stem between the same, a rotating disk carried by the valvestem to intersect the interior of the cylinders and having an openingfor the passage of the pistons and driving means connected With thepistons for causing the cylinder to alternately intersect the cylinderchamber.

In testimony whereof I aflix my signature in presence of two Witnesses.

JOHN NORIN.
